Li-ion/Li-Polymer Battery Charger

FN8692

Rev.1.00

Mar 29, 2017

The ISL78692 is an integrated single-cell Li-ion or Li-polymer

battery charger capable of operating with an input voltage

as low as 2.65V (cold crank case). This charger is designed to

work with various types of AC adapters or a USB port.

Features

• Complete charger for single-cell Lithium chemistry batteries

• Integrated power transistor and current sensor

• Reverse battery leakage 700nA

The ISL78692 operates as a linear charger when the AC

adapter is a voltage source. The battery is charged in a CC/CV

(constant current/constant voltage) profile. The charge current

is programmable with an external resistor up to 1A. The

ISL78692 can also work with a current-limited adapter to

minimize the thermal dissipation.

• 1% initial voltage accuracy

• Programmable CC current up to 1A

• Charge current thermal foldback

• NTC thermistor interface for battery temperature alert

• Accepts CV and CC types of adapters or USB bus power

• Preconditioning trickle charge

The ISL78692 features charge current thermal foldback to

guarantee safe operation when the printed circuit board’s

thermal dissipation is limited due to space constraints.

Additional features include preconditioning of an

over-discharged battery, an NTC thermistor interface for

charging the battery in a safe temperature range and

automatic recharge. The device is specified for operation in

ambient temperatures from -40°C to +85°C and is offered in

a 3x3mm thermally enhanced DFN package.

• Guaranteed to operate down to 2.65V after start-up

• Ambient temperature range: -40°C to +85°C

• AEC-Q100 qualified

Applications

• Automotive systems

• eCall systems
